Abstract

The invention discloses a content refreshing method and device for a content distribution network. By acquiring the webpage content returned to the user by the application server of the source site according to the user's access request, the static resource link in the webpage content is analyzed, and the corresponding file is linked according to the static resource. name, obtain the file version number from the collected file version data, and then use the obtained file version number to assemble the CDN access address, and the file version number in the CDN access address is different from the corresponding file version number in the CDN At the same time, refresh the content corresponding to the CDN access address in the content distribution network. The device of the invention includes a static resource link analysis module, a file version number acquisition module and a content refresh module. The method and device of the invention improve the refresh efficiency of CDN content and reduce the management cost.

Description

technical field [0001] The invention belongs to the technical field of content distribution, and in particular relates to a content refreshing method and device for a content distribution network. Background technique [0002] On the Internet, in order to improve the speed and user experience of users visiting websites, the application of Content Delivery Network (CDN) is quite extensive.
